Activate this option to ensure that certain supported constraints are exported to FBX.
FBX supported constraints include:
This option lets you export your constraints effectively without the need to bake the animation first, if you are transferring to a package that which supports these constraints, like MotionBuilder.
If you export your scene with the intention of importing it into a package that does not support these constraints (such as 3ds Max), bake the animation first. See Bake animation for more information.
